# `useLinkStatus` Hook
The `useLinkStatus` hook is primarily useful when:
- Links have `prefetch={false}` set
- Navigation occurs before prefetching has completed
- When React decides to [skip the loading
state](https://react.dev/reference/react/useTransition#preventing-unwanted-loading-indicators)
and https://github.com/vercel/next.js/issues/69625
It provides loading state feedback during these navigation transitions,
preventing pages from appearing "frozen" while new content loads.
## Usage
`useLinkStatus` can be called from any descendant component of `Link`
and it returns `{ pending: true }` before history has updated. After the
URL updates, it returns `{ pending: false }`.
```jsx
// When prefetching is disabled
<Link href="/dashboard/reports" prefetch={false}>
Reports <LoadingIndicator />
</Link>
function LoadingIndicator() {
const { pending } = useLinkStatus();
return pending ? <Spinner /> : null;
}
```
## Notes
- If the link has been prefetched, pending change will be skipped and
remain `{ pending: false }`.
- If `useLinkStatus` is not under any `Link`, it will always return `{
pending: false }`.
- `useLinkStatus` currently does not support Pages Router, so it will
always return `{ pending: false }` in Pages Router.
- When you click multiple links in a short period, only the last link's
pending state is shown
